The ends 1110 of the corrugatedplates 15 are attached to the board 14, as shown at 18 and 19, whereby arigid plate 13 is formed.

' Partition members 21 and 22 extending longitudinally and transverselyof the unit are provided for forming the cells or receptacles 11 betweenthe side plates 13. These members are connected together in a mannerwell known in the art. As shown, the partition members 21 are eachprovided with open slots 23 arranged at intervals along one edge thereofand the other partition members 22 are each also provided with openslots 24 along one edge thereof.

In assembling the units, the partition mem bers are assembled by causingthe slots 23 and 24 to engage in the manner of an egg crate therebyforming a unit having a-large number of small cells or receptacles whichare adapted to contain the insulating material. The assembled partitionsare then placed on one of the side plates 13 with the side edges of thepartitions within the grooves 16 and 17.

The cells formed by these partitions and the side plate-are then filledwith the insulating material, after which the other side plate is placedin position and secured by any suitable means, as by an adhesive or by astrip of paper extending about the unit and pasted in position, or bystaples or other fastening means.

It is immaterial how these partitions are arranged or' connectedtogether so long as they form independent receptacles for containingtheinsulating material.

Since the details of the construction of the cellular unit constitute nopart of the present invention, it is not thought necessary to furtherillustrate or describe the same.

The size of the units may vary as desired for convenience of handling.

In Fig. 7 is shown a modified form of cellular unit. In this form ofconstruction, the cellular structure 27 may be stamped or molded to thedesired shape to form cells'or receptacles 28 opening in one directionand alternate cells 29 opening in the opposite direction. Suitable sideplates 31 and 32 are adapted to be secured over the cellular structurefor closing the cells or receptacles. In charging or filling the cellsin this form of construction, the unit is placed so that one set of thecells open upwardly, and, after they are filled, the adjacent plate issecured in position as by an adhesive after which the plate is turnedover and the remaining cells filled and the adjacent side plate securedin position over these cells.

Under certain conditions, it maybe desirable to independently secure theunitsin position in the building. In Figs. 8 and 9 is shown a form ofconstruction in which this may be accomplished. The cellular unit 33 maybe substan-' tially the same as that of either of the forms describedabove and may be encircled by a layer of paper, or other suitableflexible material 34. This material is secured to the unit, as by anadhesive, and the same is provided with flaps 35 and 36 extendinglaterally from the unit, as clearly shown in Figs. 8 and 9.

When it is desired to secure -the individual units in a building, as,for instance, in a frame buildinghaving the studding or vertical framemembers 37 and 38 and the siding 39 attached to the outer side of theframe members, the unit is placed between the frame members 37 and 38into contact with the siding 39,. with the flaps extending inwardlyalong the side of the frame members, and fastening means, such as nailsor tacks 41 and 42, are driven through the fiaps 35 and 36 into saidframe members.

When this form of construction is used as insulation for the side wallsof frame buildings, the units, of course, are arranged in tiers betweenthe vertical frame members of the building and the tiers are separatedby those frame members.

In Figs. 10 and 11 is shown a modified form of construction especiallyadapted for use in rooms or buildings where sound insulation is of primeimportance.

In this form of construction, each unit 40 comprises a back plate 43similar to one of the side plates 15 in the form of constructionpreviously described and which is provided with intersecting grooves 44which are' adapted to receive the edges of the partitions 45 and 46, asin the previous construction. The cells or receptacles 47 formed by thepartitions 45 and 46 are adapted to contain insulating material 48 whichmay be the same as the insulation used above. After the cells 4'7 havebeen filled with the insulating material 48, a foraminous member 49 isplaced over the cells for holding the material in position therein. Theforaminous member 49 may be of any suitable material, such as muslin,wire netting or the like. The plate 43 may be reinforced by a member 51ceiling 52 of a room or building 53, they are placed inalignment againstthe lower surface of the ceiling and are held in position by grid panelsor other open or lattice wprk 54.

These panels are held in position by suitable fastening means, such asthe screws 55, which pass through one of the grids 58 and either throughor between two adjacent sound insulation units 40 and into the ceiling52, as clearly shown in Fig. 10 of the drawings.

These sound-insulating units may also contain material, such as expandedvermiculite, that is also a heat insulating material. A wall build ofsuch material will not only prevent the escape of heat from the room butwill also not transmit sound through the wall.

I claim as my invention;

1. An insulation for a wall of a building comprising a plurality ofinsulating units, arranged in alignment alongside said wall, each unitcomprising light rectangular plates parallel and spaced apart, andhavinggrooves therein, the light partitions extending at right angles toeach other and interlocked, the partitions extending in one directionbeing seated in said grooves, the space between said plates beingdivided into comparatively\small receptacles and light insulatingmaterial within said receptacles, said material comprising dividedparticles.

2. In combination, a building having a wall, insulating units comprisinga back plate, partitions engaging said back plate and forming therewitha plurality of smallreceptacles, insulating material within saidreceptacles, a sheet of reticulated material across the open ends ofsaid receptacles and a grillacross the front of said reticulatedmaterial.

3. An insulating unit comprising a back plate 1,957,829 and forming withsaid first-named partitions and with said back plate a plurality ofcomparatively small receptacles, insulating material filling saidreceptacles, a sheet of material secured over the 'front of said unitfor closing said receptacles and another sheet of material secured'overthe back of said unit whereby a plurality of dead air spaces will beformed between said back plate and lastnamed sheet. 1
